1_{Denotes that ‘size’-times one byte is transferred on the serial flash data bus. Total number of bytes must be pro-}
vided in the TX Buffer or can be read from the RX Buffer
2_{According to Winbond documentation this command only supports a maximum clock speed of 50 MHz. If the}
Serial Flash is operated at a higher clock frequency, the clock frequency for this command must be decreased. Refer
to Section 30.7.2, Serial Flash Clock Frequency Limitations” for details.
The following table shows only the upper 3 bytes of register QSPI_ICR, byte 0 contains the Instruction
Code. All sizes in Byte 2 are interpreted as the number of bytes, the number of sclk clocks required in the
transaction will be calculated by multiplying with 8 and dividing by number of data lines.
